you can use >= and <= too. legal qualifiers, you specify the set of
possible operations. for instance with boolean filters, you say
only,excluded. In most cases, it should be the same as qualifier except
the one i stated above. Although, I believe, the software should work
without these but for martservice, these are useful for serving meta
data of your mart. Try using ensmebl mart's dataset gene_ensembl as
example, its quite rich.
